Well I was debating 4.11 or 4.56 a while back and was convinced to get 4.56 gears with my 35x15 tsls. I haven't finished putting everything back together yet but recently drove a friends bronco with a 3spd manual, 4.56 gears and 35s and it seemed like it was geared wayyyyyyy too low. The rpms in 3rd gear going 32-36 mph sounded like what they should going 55. Nearing project completion I want to get more streetable tires, and my debate is to step up from the originally planned 35x12.50 to 37x12.50. The main debate is that for some reason tire manufacturers think its a good idea to bump the tire price up $200 more per tire so I'm looking for justification. Anyone running 4.56/37x12.5 on a C4 auto 3spd? What do your rpms look like at 55mph? Or anyone know how big of a difference 35 vs 37 would make? Any info is appreciated.
